Two people can have a conversation by using a the Systran Translation Project part of the Systran Translation software.
Sometimes you want to have a conversation with a person who speak another language and truly translators put words in your mouth that are not needed.
Goal: I want to talk with a French speaking person in Ivory Coast:
1. Two people who can read.
2. Systran Program
3. Start two project, one that is French to English and another that English to French.
Simple enough, when I type in English and it translates to French, when my friend want to say something she types in French and translates it to English.
Warning: Please take care with this, you can lose friends that do not read, try to discover if the person can read and write before you start.
